Filipino tech entrepreneur Diosdado “Dado” Banatao died at the age of 79.
Banatao is known for pioneering the technology that made personal computers possible, thus putting Silicon Valley on the map. He also co-founded three technology companies and started a nonprofit to help support Filipinos in STEM fields.
“Rising from humble beginnings in Cagayan, he went on to co-found transformative technology companies and played a pivotal role in advancing the global semiconductor and graphics industries,” said the National Federation of Filipino American Associations on LinkedIn in honor of Banatao’s passing. “Just as importantly, he invested deeply in people opening doors, mentoring founders and strengthening communities.”
According to a post on his website by his family, Banatao passed away peacefully on Christmas Day, surrounded by family and friends. His family said he “succumbed to complications from a neurological disorder that hit him late in his life.” He would have been 80 in May.
His family wrote, “We are mourning his loss, but take comfort from the time spent with him during this Christmas season, and that his fight with this disease is over.”
Banatao was born to a rice farmer and housekeeper in Iguig, Cagayan, according to ABS-CBN. According to his 2015 documentary, he didn’t have access to electricity growing up and was taught math using bamboo sticks. He said it was typical for his classmates to stop going to school after sixth grade to help their parents work in the fields, but his father told him to continue studying.
He developed a love for engineering and graduated with a degree in electric engineering from Mapua Institute of Technology, a private research university in Manila. He said in his documentary that there were no design jobs for engineers in the Philippines, so he moved to the U.S. and pursued a master’s degree in electrical engineering and computer science at Stanford University. He graduated in 1972.
Soon after college, Banatao worked as a design engineering at Boeing. ABS-CBN reported that he then went on to work for other technology companies, like National Semiconductor and Intersil. While at Commodore International, he designed the first single chip, 16-bit microprocessor-based calculator.
He is credited with developing the first 10-Mbit ethernet CMOS chip in 1981 while working at Seeq Technology. He also developed the first system logic chipset for IBM’s PC-XT and PC-AT and one of the first graphics accelerators for personal computers. These inventions allowed for faster computer performance, according to Inquirer.net. The Harvard Club of Southern California credited Banatao for bringing GPS technology to consumers.
“Dado is the man who invented a graphical chipset that took us from black screens with green writing to the dynamic displays we have today,” the club wrote for a description of a lecture he gave in 2017 for the Harvard Business School Association of Orange County.
Banatao founded the chipset company Mostron with a business partner in 1984. One year later, he also co-founded Chips and Technologies, a graphics adapter company that Intel later acquired for around $430 million.
The CEO of Intel, Lip-Bu Tan, expressed his grief at Banatao’s passing on LinkedIn, crediting his friend for challenging him when he became CEO of Cadence Design in 2009.
“I am forever grateful for your challenge and encouragement as I continue my life journey following your footstep as CEO of Cadence Design for 12 years and continuing as CEO intel,” Tan said in his post. “Dado, you are the best technology entrepreneur and legend from (the) Philippines.”
He then founded S3 Graphics in 1989, which led the local bus concept and developed Windows accelerator chips, becoming the third-most profitable technology company in 1993. In 2000, Banatao entered the world of venture capital by founding Tallwood Venture, a firm focused on investing in semiconductor technology, and served as managing partner.
While working at Tallwood in 2011, Banatao told Bloomberg News that he encouraged his companies to expand internationally, focusing particularly in China, due to greater government support and lower production costs.
“It used to be that we started companies here and we didn’t think about going offshore until we were substantially big,” Banatao said when he was 64 at his office in Palo Alto. “At the outset now, as we fund the company, we think about going outside right away.”
Dinakar Munagala, co-founder and CEO at Blaize, Inc., a computer hardware manufacturer in El Dorado Hills, wrote on LinkedIn that he was “deeply saddened” by Banatao’s death.
“Dado was instrumental in shaping Blaize during its formative years,” Munagala said. “His belief in our mission, steady counsel, and generous spirit left a lasting mark on all of us who had the privilege of learning from him.”
Banatao has received several awards and recognitions for his contributions, including the Pamana ng Filipino Award in 1997, Asian Leadership Award in 1993, and the Ramon V. Del Rosario Award in 2018, according to ABS-CBN. In 2003, the Asian American Activities Center at Stanford recognized Banatao in the university’s Multicultural Alumni Hall of Fame.
Inquirer.net also reported that an institute at the University of California bears his name: the Banatao Institute at the Center for Information Technology Research in the Interest of Society.
Banatao founded the Philippine Development Science and Technology Foundation, a nonprofit also known as PhilDev that provides scholarships, mentorship and training programs to young Filipinos in STEM fields. His family urged people to donate to PhilDev in Banatao’s memory.
“We (Filipinos) know hardship,” Banatao said in his documentary. “It’s time we learn success.”
